Avian penicilliosis caused by Penicillium griseofulvum in a captive toucanet.
A sudden fatal illness developed in a group of New World toucanets held captive in Finland. Necropsy studies on one of the birds revealed the presence of invasive, hyaline, septate, branched mycelium in the lungs, air sacs, liver and other tissues. In addition, conidiophores and conidial chains, typical of members of the genus Penicillium were present in the lungs and air sacs. Cultures yielded a mould which was subsequently identified as Penicillium griseofulvum. A critical review of the literature revealed that only seven other species of Penicillium have been convincingly documented as agents of penicilliosis on the basis of histologic and cultural findings.
